I posted a question here a couple of weeks ago asking if anyone knew of a source for plans to build a prop speed reduction unit for a Volks conversion. I posted this in the portion of this site that deals with Volks engines and have had no replies yet. If I ask the question again here maybe I'll reach a bigger audience and have better luck. Any replies about doing this, pros and cons versus one of the factory PSRUs would be of interst too. Thanks.
